Protocol for isolation of interstitial fluid from tumor-draining lymph nodes for proteomic profiling in murine breast cancer models.
Article in STAR protocols, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Tumors release soluble factors that reach tumor-draining lymph nodes (TDLNs), where they induce remodeling already at the pre-metastatic stage and alter the local proteomic landscape. Here, we describe a protocol for isolating interstitial fluid from primary tumors and TDLNs in murine breast cancer models to study extracellular protein composition while preserving tissue viability and integrity. We outline key steps for tissue preparation, fluid extraction, and downstream bioinformatic analysis to support the characterization of tumor-associated changes in TDLNs. For complete details on the use and execution of this protocol, please refer to Mattavelli et al.
